ABSTRACT:
The invention relates to a production process of a composite material composed of aggregates of a blend of UO2and of PuO2dispersed in a UO2matrix comprising the steps of dry co-grinding of a UO2powder and of a PuO2powder in order to obtain a homogenous primary blend, of consolidating the primary blend in order to obtain cohesive aggregates, of sieving the aggregates in a range of 20 to 350 μm, of diluting the sieved aggregates in a UO2matrix in order to obtain a powder blend, of pelletising the powder blend and of sintering the pellets obtained in order to obtain the composite.
